Apparent component and True component
Aspen Plus Help 文档解释:As a result of the solution chemistry, a set of true species is present in the liquid phase that differs from apparent molecular components. Apparent or parent components are present in the system if no reactions occurred. For example, the sour water stripper system has three apparent molecular components: water, ammonia, and hydrogen sulfide. The three molecular components dissociate in the liquid phase.
个人理解:当用户在components里规定了离子时,才有apparent component 和 true component的区别,true component是只溶液里各个组分,包括了离子。而apparent component是已经将离子map成了分子,也就是说不能显示离子的组成。
在property环境下,导航至Properties,Global页面有一个Use true component的复选框,来决定模拟是否ture component。在Radfrac的block option节点下,Properties页面里,有一个Simulation approach下拉框,用来选择true component和apparent component。
好的,在一般的离子模拟中,往往是即想查看true components,也想查看apparent component,那该怎么办了?
那就使用true component来进行模拟,然后加property set来显示apparent component,例如XAPP(摩尔分数),FAPP(摩尔流量),TFAPP,TWAPP。
